For several years, it is always about me. Excellent audio quality, nothing to do with dictaphones despite a very small size. and remarkable sensitivity. Saves an interview perfectly leaving it just beyond his pocket like a lavalier microphone, no need to shake under the nose of his interlocutor! Can record music live, but it is not all the same studio quality! A bit limit for the classic live, unless you place the camera on a walk near the musicians. Quite suitable for a music teacher to record his students excellent sound quality. Not suitable as micro spy: he has a big red light when lit! Large recording capacity (tens of hours!) USB connectable and direct to read files on a USB key as both the Mac and PC. Never had any problems. For editing sound, I use Audacity (free software) remarkably effective and powerful.
Battery has reliable air, I finally replaced as a precaution but it still lives on another device.
